Thermal Imaging & Infrared Cameras

Posted on

There is a wide variety of uses for Thermal imaging cameras or infrared cameras depending on the information required for a particular task. It is important to understand the differences between these types of camera’s and what they are capable of before investing in equipment which may not be suitable in the application they are required for.

Infrared cameras differ from thermal imaging cameras as they use short wavelength infrared light to illuminate the required location or point of interest and as fragments of the infrared energy gets reflected back into the camera it is then turned into an image via the camera’s internal logic interpreter. This type of camera is often referred to as an Active IR System.

Thermal Imaging Systems are essentially branded as forward looking infrared with one leading manufacturer FLIR stealing a march on other companies by using the initials as their brand name although other companies such as Fluke and Seek Thermal would also use the same technology for their thermal imaging cameras. Thermal imaging cameras are passive sensing differences in heat through the use of mid or long wavelength infrared energy. The thermal imager is a non-contact camera designed to detect the infrared energy or heat from an object or surface converting it into a visual image which can be interpreted for the results required. Standard camera’s and the human eye work off of the logic of visible light energy bouncing off something being detected and converted into an image whereas thermal imaging cameras make their images from heat and not visible light. Standard cameras will not see thermal energy, only being able to detect visual light although some models of thermal imaging camera can offer a frame in frame set of images with one standard image as you would normally see it and the thermal image showing the infrared or thermal energy so people can use these differing images as reference points which can be incorporated into thermal imaging reports.

There are infinite uses for thermal imaging and infrared cameras depending on their specification and to be qualified as a thermographer from an insurance perspective there is a requirement for formal certified thermal imaging training to be completed. Thermal imaging training in Ireland is designed to ensure the correct use of these types of devices and that information and results are being determined accurately.
